Application filed February 20.1825.

T (@ZZ whom 275 may concern:

lie it known that John TAYLOR, a citizen of the United States, residingat Salt Lake City, in the county of Salt Lake and State of Utah, hasinvented certain new and useful Improvements in Blowers, of which thefollowing is a specification.

This invention relates to blowers of the fan type and it has for itsobject to provide an improved device of this character adapted todevelop great efliciency in use.

In the accompanying drawings:

Figure 1 is a vertical sectional view of a blower constructed inaccordance with the invention.

Figure 2 is a side view thereof, with one half of the casing removed.

Figure 3 is a fragmentary view of a portion of the rotor.

Figure 4 is a fragmentary View of a modified form of the rotor, and

Figure 5 is a sectional view of a form of stationary elementcorresponding to the structure of Figure 1 with certain modificationsincorporated therein.

Like numerals designate corresponding parts in all of the figures of thedrawings;

In the drawings 5, designates a casing havin an enlarged tubular hub 63.Spokes 7 support bearings 8 from the hub 6, and said bearings 8 serve asa mounting for the shaft 9, to which rotation may be imparted by thepulley 10. A sleeve 11 is fast upon the shaft 9 and through. the mediumof the spokes 12, supports collars 13, constituting extensions of theinner vanes 14 of the rotor. The web of the rotor is indicated at 15 andthe rotor comprises, in addition to the inner vanes 14, outer vanes 16.Statioln ary vanes 17 are secured to the casing 5, at 18 and these vanes1'? include flanges 19, which prevent air from finding its way into thespaces 20, outwardly of the vanes 16 and compel the air to pass throughsaid vanes 16.

In operation the air enters through the hub 6 and is thrown outwardly bythe vanes 14. It is caught and its rotary motion is checked by the vanesv17, the inclination of said vanes being such as to continue the outwarddirection of movement of the air. The air is then discharged into thepath of movement of the vanes 16, by which it is thrown outwardly withgreat force into the restricted portion 20 of the casing, from "SerialNo. 16,612.

whence itis discharged through the outlet port 21 into any suitableconduit.

It is a well known'fact, that when the whole body of air, in the casingof a fan of this sort, gets to whirling with the rotor much of theefiiciency is lost. By the disposition of the vanes 17, intermediatevanes 14: and 16, the whirling motion of the air is broken up and theefliciency of the apparatus is correspondingly increased.

In Figure 3 I have illustrated a method of mounting the vanes upon therotor. In this case the rotor indicated at 15 carries vanes 15 whichcomprise plates 16 that are secured to the rotor 15 fastening devices,indicated ure 4 the structure is much like that illustrated in Figure 3and like reference numerals have been applied, except that in this case,the outer portions of the vanes 15 are tied together by a plate or strip15 In the modification illustrated in Figure the casing 5 carries thebearing 5* for the shaft of the rotor (not shown) and said casing alsocarries a plurality of vanes 5 which correspond to the vanes 17 inFigure 1. However, the structure differs from Figure 1 in that the airis taken entirely from one side of the casing, viz through the hub 5.Partitions 5 prevent the passage of the air from the left hand side ofthe casing to the right hand side thereof (this partition bein completedby the presence of the rotor disc when the later is in place) and theair is compelled to follow the path of the arrows in Figure 3, travelingfrom the left hand side of the partition through a conduit 5 and passingout of the casing through a discharge port 5 Itis to be understood thatthe invention is not limited to the precise construction set forth butthat it includes within its pur view whatever changes fairly come withineither the terms or the spirit of the appended claim.

Having described my invention, what I claim is:

A device of the character described comprising a casing having anenlarged, centrally disposed open hub, spokes carried. thereby, bearingscarried by said spokes and held thereby in spaced relation to the hub topermit of the entry of air between the hub and bearings, a shaft mountedin said bearings, a rotor carried by said shaft, a set of at 15 In Figby any suitable inner 'anes carried by said rotor and comprisingsubstantially horizontalcollars which project into the hub of thecasing, outwardly of the bearings, a second set or vanes disposedoutwardly of the first set of vanes and spaced therefrom and anintermediate stationary set of vanes carried by the casing, the vanes ofthe rotor being spaced from each other, with openings therebetween whichpermit the passage of air inwardly through the horizontal collars to theinterior of the rotor and thence radially outward between the vanes.

In testimony whereof he affixes his signatnre.

JOHN TAYLOR.
